Troubleshooting
High Organic Load, Low Phytoplankton
01 — Overview
What this protocol is for
An 8-day extended corrective schedule for conditions where high organic load is combined with low phytoplankton. Days 1 to 5 follow the phytoplankton crash, BGA, and overbloom protocol exactly. Days 5 to 7 add FytoGro and BactoGro to gradually rebuild phytoplankton alongside continued molasses. MinGro at 0.5 ppm is applied from Day 2 for 7 days.
Primary Objective
Reduce organic load, correct ammonia, and gradually re-establish a stable phytoplankton bloom using an 8-day extended product schedule.
02 — Indications
When to use this protocol
All pond types, both species, during grow-out when high organic load is combined with low phytoplankton
Important Notes
- !
Keep aerators running continuously. High organic load creates high BOD and low DO risk.
- !
This is an extension of the 5-day phytoplankton crash protocol. Do not skip Days 1 to 5 and go directly to the FytoGro phase.
